Formerly known as ZEIT, Vercel has a lot to offer in the serverless movement.
ZEIT was one of the pioneering companies at the time pushing Serverless technology. ZEIT’s first focus was to ease deployments, which resulted in the creation of Next.js.
Some of Vercel’s customers include AirBnB, Auth0, GitHub and the Washington Post.
Vercel announced a whopping $21M Series A funding early 2020.
Fly is an opensource runtime for edge apps, Fly offers a paid hosted version of their product as well. This provider will focus on the paid hosted version. Fly.io is one of the few companies and products that has a full range of tools alongside their actual product, which makes them an ideal candidate for curious developers and new companies to experiment.
Everything they do is docker based, and their networking abstraction is top notch, it’s clear Fly will play a major role in turning the space into a more user-friendly one. Fly’s ambitious mission to make application distribution as ubiquitous as CDNs sets the bar for any contenter willing to compete.
